1 / 4 page 1 HYFIRE® VIIS SPORTSMAN CD IGNITION SYSTEM Part No. 667S 412 Cylinder Notice: This product is legal for sale or use only on vehicles which may never be used on highways. The HYFIRE® VIIS Sportsman CD Ignition Controls are not compatible with distributorless systems or positive ground applications. The RPM Limiter in the HYFIRE® VIIS Sportsman CD Ignition Controls will not work properly with odd-fire or semi-even fire V6 applications. The HYFIRE® VIIS Ignition System is not designed for marine use. GENERAL INFORMATION The RPM limiter in the HYFIRE® VIIS Ignition System is not recommended as an engine speed governor. The use of the RPM limiters is not recommended for applications equipped with a catalytic converter. Similarly, forcing engine RPM past the RPM limiter continuously for long sustained intervals can cause problems resulting from fuel build up in the exhaust system that may adversely affect the application. Ignition Ballast Resistor / Loom Resistance Wire The HYFIRE® VIIS Ignition Ignitions performance is not affected by the presence of the factory ignition resistors or ignition ballast resistors in the wire from the ignition switch. It is not necessary to install ignition ballast resistors as specified by the instructions for the particular distributor. Ignition Coils The HYFIRE® VIIS Ignition System is designed to work with Mallory PROMASTER® Coil Part No. 28880. Avoid using any other type of ignition coil. Spark Plug Wires YOU MUST USE suppression type (carbon core, spiral core) spark plug wire. We recommend spiral core ignition wire, such as Mallory PRO SIDEWINDER® Ignition Wire. Suppression type spark plug wires prevent false triggering and the possibility of premature ignition or accessory failures. DO NOT USE solid core (copper core; stainless steel core) spark plug wire with any electronic ignition system or accessory. Solid core spark plug wire is a source of ignition noise, which can cause false triggering and premature ignition or accessory failure. Spark Plug Gaps For street applications, use your engine manufacturers specifications. For racing applications, start with your engine manufacturers specifications, then experi- ment with the plug gap to achieve maximum performance. Electric Welding Disconnect the HYFIRE® VIIS Ignition System and unplug any distributor harnesses (if possible) before any welding is done on the vehicle. External RPM Limiters Mallory RPM Limiter Part Nos. 641-4, 641-6, 641-8, 642, 643 and 644 WILL NOT function with the HYFIRE® VII Ignition Systems. Mallory PRO TACH® I, IV and IV The tachometer and shift light will work with the HYFIRE® VII Ignition Systems. However, the RPM limiter WILL NOT function with the HYFIRE® VII Ignition Systems. Turn the LIMIT RPM knob slightly past 11,000 to prevent the RPM limiter from interfering with the tachometers other functions. MOUNTING PROCEDURE Step 1 Disconnect the battery () cable to cut power to the system. Step 2 Select a convenient location to mount the HYFIRE® VIIS Ignition System. Keep the unit away from hot engine components or extreme heat such as the exhaust system and manifolds. Keep the unit away from moving devices, such as fans, belts and linkages. The location must be dry. Moisture will damage components inside the unit. Step 3 Mounting to a flat surface with shock mounts Hold the unit in its mounting position and center punch the mounting pattern on the mounting surface for drilling mounting holes. Drill mounting holes using a 9/ 32" drill bit. Install the shock mounts into the bottom plate of the unit. Hold the unit in position where it will be mounted. From the backside of the mounting surface, insert the washers and the 1/4-20 nylock nuts onto the shock mount studs. Tighten each nut until snug. INSTALLATION INSTRUCTIONS ® FORM 1468 (REV. B) 9/00 |
